村落文化传承和发展的困境、意义和重构   总被引:1,自引:0,他引:1  
柳丽 《中国农学通报》2019,35(16):159-164
村落是中国传统社会的独特意蕴,是村落文化形成的基础和重要载体形式。随着城镇化建设的推进,村落文化面临文化发生断裂、文化根基动摇、文化生态格局被瓦解和村落文化传承出现危机的困境。村落文化有助于形成村落共同体意识和维护村落自治格局,助推村落共同价值观念的形成和中华传统文化的传承。重构村落文化,需要建构科学有效的管理体系,建立多元化的资金筹措机制,制定切实可行的法律法规,协调城镇化建设和村落发展的关系。传承和发展村落文化,需要处理好保护和发展的关系,在保护中提升发展的质量。  相似文献

试论中共领导核心关于粮食思想的继承和创新   总被引:1,自引:1,他引:1  
“民以食为天,食以粮为源”。抓好粮食这个基础性、战略性资源的生产和供应,对中国这个人口大国的重要性不言而喻。通过评述中共领导核心关于粮食问题的忧患意识,既归纳了他们在处理粮食与工业的关系方面所持政策思想的传承性,即坚持农业的基础地位不动摇;又分析了中共领导核心紧扣中国国情,在调动农民的生产积极性方面所提出的办法以及在如何加快粮食增长方面所采取的方式,他们的粮食政策思想有颇多创新之处;在对中共领导核心粮食思想进行比较论证的过程中,提出了在保持农业政策连续性和稳定性的基础上,依据国内外形势变幻不断创新粮食理论的观点。  相似文献

The construction of characteristic towns is in full swing under the guidance of policies.There have been many outstanding achievements, but many problems are also exposed.Especially for towns with traditional ancient villages, when characteristic towns are built, there is not enough attention to the original traditional architectural culture, or the style is inconsistent and uncoordinated after construction.Based on this, taking the construction of history and culture exhibition hall of Qianhouwan Village in Sanjiang Town of Nanchang County as an example, this paper introduces the design and actual construction situation, and elaborates the inheritance of traditional architectural culture under the background of characteristic town construction in Sanjiang Town.  相似文献

水稻成熟胚培养高效再生系统的创新   总被引:5,自引:0,他引:5  
本文测试了不同消毒方式、愈伤组织诱导、绿苗分化及生根条件对不同类型水稻成熟胚培养再生成株的影响。研究结果表明:改良培养基比基本培养基处理效果更好,在改良培养基N6I愈伤诱导、MSR绿苗分化和MSC生根条件下,籼稻(O.sativa indica cv.滇屯502)、粳稻(O.sativa japonica cv.日本晴)、籼粳杂种F1(滇屯502/日本晴)和非洲栽培稻(O.glaberrima cv.RG105)的诱导率分别为96%、100%、98%和100%,成苗率分别为264%、286%、216%和224%。以YuhanClorox(4%NaClO)稀释一半消毒1h效果最好。由此建立了一套非常高效、可靠、重复性好的适用于不用基因型水稻成熟胚再生系统,为水稻遗传转化和多倍体化的顺利进行奠定了基础。  相似文献

Different Pelargonium hybrids are of great importance to horticulture. Breeding; for F1 hybrid and clonal eultivars is particularly prevalent in Europe, Japan and North America. The results of a great deal of breeding research are scattered throughout different journals and published in several different languages. The aim of this review is to summarize the results of research on interspecific crosses and the inheritance of flower and leaf colour, plant habit, resistance and floret type.  相似文献

Summary Heritability in the broad sense and the distribution of levels of winterkill were analyzed in the offspring from hardy diploid and from hardy, semi-hardy and tender tetraploid roses. The heritabilities for different parental combinations ranged from 51 to 92%.The offspring from crosses of hardy parents were also hardy and showed little variation in hardiness levels. The offspring from crosses of hardy roses with the semi-hardy R. kordesii and the tender Queen Elizabeth survived the winters without coverage but showed a wider variation in hardiness levels.The desirable level of hardiness, an average winterkill of less than 10%, could be achieved through selection in the first or second generation of breeding, depending on the hardiness levels of the parents. The hypothesis is advanced that winterhardiness in roses is controlled by very few or closely linked genetic factors.Contribution No. 557  相似文献

Inheritance of aroma in rice   总被引:7,自引:0,他引:7  
E. Tsuzuki  E. Shimokawa 《Euphytica》1990,46(2):157-159
Summary Inheritance of an aroma was worked out in crosses between Brimful from Nepal as an aromatic rice and leading Japanese varieties Koshihikari and Nipponbare as non-aromatic ones. The F2 pattern of segregation for aroma to non-aroma was 3:13 indicating one dose gene for aroma and one dose inhibitor gene in two crosses. This ratio was confirmed by genetic behavior of F3 populations.  相似文献

The data collected by Johnson and Paul (1958) from five crosses for the study of the inheritance of earliness in barley have been re-analysed by following biometrical techniques as developed by Mather (1949).Earliness in barley was found to be controlled by polymeric genes. Two to five effective factors were estimated to be operating, affecting earliness in the various crosses.Presence of overdominance was observed in three of the five crosses, while in the remaining two crosses no dominance was noted.Transgressive segregation was observed in the two crosses, Frontier x Bonneville and Montcalm x Atsel. The cross, Montcalm x Atsel, may be a source for breeding a new strain which might be expected to mature earlier than the early parent, Atsel.University of Alberta Postdoctorate Research Fellow  相似文献

Inheritance of scent in rice   总被引:15,自引:0,他引:15  
Summary Inheritance of scent in rice and its association with pigmented characters were studied in T-141 × K-44-1. Four complementary genes appeared to control scent, one of them showing linkage with a complementary gene for glume colour and a supplementary gene for red pigment in apiculus. This group formed part of V (Prp)linkage group of Misro et al. (1966) in which case Pg and P were additions.Pl.480 Project on linkage maps in rice.  相似文献

Farming culture is the main part of Chinese outstanding traditional culture and also the important spiritual and cultural resources to construct the core values of the Chinese nation. In the new era, fully exploring and making full use of farming culture resources has important practical significance for the protection, inheritance and innovation of Chinese excellent traditional culture. The rapid development and successful brand shaping of Hani terrace tourism could provide experience for the exploration and utilization of farming culture tourism resources in other areas of China. Based on the analysis of development process of Hani terrace tourism as well as the successful experience of other regions for reference, ideas of developing farming culture tourism in the Dabie Mountains were proposed.  相似文献
